[laddu]

hello,

I am encountering some high load on my server:

Found some similar threads where the solution was to upgrade php. I am currently with the latest php version as you can see:

Code:

php -v
PHP 5.2.6 (cli) (built: May  7 2008 00:50:43)
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

I can see that php-cgi is causing the issue. Any idea about I can resolve this ?

Regards
